"I’ve worked with hundreds of freelancers over the last 10+ years, and Alexandra is truly one of the standouts." - This is what clients say about me Hey, I'm Aleksandra 👋 I help both early-stage and growth-stage companies turn product and marketing data into actionable business insights. Over the years, I've developed my own methods, frameworks and templates using best practices, which means I can take on multiple clients without compromising on quality or speed, and you get senior-level work at a fraction of the usual turnaround time. Slow response times is one of the biggest frustrations clients come to me with, and I've automated my workflow specifically to fix that. My clients stop flying blind on paid acquisition and user behavior. After working with me, they have dashboards they actually use, funnels that surface real drop-off, and a clear picture of what's driving or killing revenue. I'm the right fit for you if you... • Need an audit of your current analytics implementation • Want to turn messy data into clear decisions • Would like to implement an analytics tool but don't know where to start • Have set up analytics but don't know how to use it effectively • Want assistance in creating dashboards, reports, charts or funnels • Need to understand drop-off rates and churn • Would like to set up experiments or A/B testing • Need to understand the performance of Google / Meta / TikTok / Reddit Ads • Need someone to provide training or workshops for your internal team With 70+ completed projects and $300K+ earned on Upwork, I bring both the technical depth and business context to make analytics actually useful. Tools I work with: • PostHog • Amplitude • Mixpanel • Google Analytics • Segment • Lovable • RevenueCat • Adapty • AppsFlyer • CustomerIO • Klaviyo • Claude Code • n8n • Make To start working together simply invite me for an interview or book a consultation and let's discuss your project.

Hello! I’m a UX/UI & Product Designer with a background in Full Stack Development, specializing in modern web experiences, SaaS platforms, dashboards, and brand-driven digital products. My combination of design expertise and technical knowledge allows me to create interfaces that are not only visually polished, but also strategic, user-centered, and development-friendly. I work primarily with Figma and specialize in UX/UI design, responsive web design, design systems, branding, and high-converting user experiences. Over the years, I’ve worked on projects across multiple industries including AI-powered platforms, cybersecurity, e-commerce, fintech, luxury wellness brands, and educational products. My experience includes designing dashboards, mobile and web applications, marketing websites, email campaigns, and complete visual identities. My design process focuses on understanding both user behavior and business goals to create intuitive, scalable, and engaging digital experiences. From wireframes and user flows to polished interfaces and branding systems, I ensure every detail contributes to a cohesive and effective product experience. What makes me different is my ability to bridge the gap between design and development. With years of experience as a developer, I understand technical constraints, responsive behavior, and how to collaborate efficiently with engineering teams — helping projects move faster and more smoothly from concept to launch. If you’re looking for a designer who combines strategy, aesthetics, and technical understanding to create impactful digital products, I’d love to collaborate. Let’s build something great together.

Every week, I talk to founders stuck in the same loop: agencies dragging for months, developers ghosting mid-project, budgets disappearing, and no launch. Recent win: Took a founder's idea from Lovable prototype to a live SaaS, Heardly, which scans billions of social posts across Reddit, TikTok, Instagram and LinkedIn to find people already asking for their product, then writes a ready-to-post comment reply for each conversation. AI-powered scans, Stripe billing and competitor monitoring I’m Ilyas, you speak directly to me, i execute fast, and i ship. no layers, no miscommunication, no surprises. I specialise in building real products fast using Lovable, Replit, Supabase, Claude Code, Cloudflare, Vercel, React, Next.js and TypeScript... From proof of concept to MVP to live product, delivered very faster than a traditional dev team, without compromising on structure, security, or quality. Message me directly for a free 30-minute consultation. I’ll review your project, tell you if I’m the right fit for your project, if not i will give you practical advice to find the right talent your project.
